CHEMETAL USA is a respected manufacturer and worldwide supplier of tungsten plates, tungsten sheets, and a wide variety of their milled end products. We are capable of machining tungsten plates and sheets within a range of thickness from 10 inches (25.4 cm) to less than 0.004 inches (0.1 mm). All our products meet stringent quality control standards at every stage of production, from rolling and annealing to surface treatment and testing.

Each tungsten plate or sheet is produced to exacting standards of performance, purity, dimension, flatness, and surface condition. Tungsten plates and sheets, sometimes alloyed with other metals, are compacted and sintered into ingots by powder metallurgy. The ingots undergo a further series of heatings, rollings, and millings to yield finished products per customer specifications.

    Our knowledgeable engineers work closely with our customers to tailor the product’s parameters to the customer’s requirements. The tungsten plate products offered by CHEMETAL USA are under close inspection and quality control of the microstructure, recrystallization behavior and the mechanical, chemical and physical properties. We worked hard to optimize the sintering and rolling processes in order to cost-effectively achieve a high production yield and homogenous microstructure.


    Tungsten Alloy Plate And Sheet (WNiFe, WNiCu, WCu)

    WNiFe, WNiCu Plate And Sheet

    Tungsten heavy alloy plate and sheet contains tungsten content ranging from 80%-98% with small amounts of molybdenum, nickel, iron and copper elements. After going through the mixing, pressing and sintering process, Tungsten is alloyed with other metals beginning as a form of powders. 16.5-19.0 g/cc density of tungsten heavy alloy is the most important industrial property.

    Tungsten Heavy Alloy Plate is an important material in the aerospace, military, medical industries. It is because that tungsten heavy alloy plate is characterized by low thermal expansion, high density, radiation absorption and high thermal and electrical conductivity. It is a common material chosen out of all the various hardness and wear resistance materials used for producing machining tools including lathes and dices. At the same time, it can also ensure perfect performance in high radiation exposure environment. Tungsten heavy alloy gives excellent service in applications requiring a remarkable performance in corrosion resistance, density, machinability and radiation shielding. Therefore, this makes it ideal for use in specified steelmaking, mining, aerospace and medical industries. More about tungsten heavy alloy plate and sheet>>>


    Tungsten Copper (WCu) Plate And Sheet 

    Tungsten copper plate and sheet are preferred flat materials for high voltage and high temperature applications, resistance welding and EDM applications. This is due to its excellent thermal and electrical erosion resistance, as well as its conductivity, low thermal expansion, and good machinability. Pure tungsten has a high thermal strength and melting point. Copper has an excellent thermal and electrical conductivity and is also much easier to machine than tungsten. Tungsten copper plate and sheet consists of tungsten and copper at varying W and Cu ratios which mainly includes 50/50, 60/40, 70/30,75/25, 80/20 and, 90/10.  The wide range of ratio compositions allows copper tungsten materials to be easily tailored to conform to distinct physical and mechanical properties upon different requirements.

    Tungsten Plate Applications

    • Heat resistance components: heat shield, heating element of high temperature vacuum furnace
    • Tungsten sputtering targets for the vacuum coating and evaporation coating
    • Electronic and semi-conduct components
    • Ion implanted components
    • Tungsten boats for sapphire crystal furnaces and vacuum furnaces

    High Temperature Furnace

    Tungsten plate has a high heat resistance. Its high melting point allows it to serve well as the material in high-temperature furnace components. Heating elements, heat shields and boats of high-temperature furnaces are required to be resistant to a working temperature up to 1300 °C. Therefore, all of them are mainly made of tungsten plate and tungsten sheet. In the metallurgical industry, some components of electric-resistance furnaces are made of tungsten flat products. These furnaces are used to sinter refractory metals into billets and semi-finished products. The refractory metals include tungsten, molybdenum, tantalum and niobium.

    Tungsten heating elements are the core part of high temperature furnaces. The working temperature can rise up to 2800°C and stay in 2300 -2350°C for a long time. The heating element is usually in the shape of a cylindrical shell or pieces of closed-end tungsten sheets riveted by tungsten bolts. Tungsten heat shields are the heat insulating part of high temperature furnaces. The riveted tungsten sheet is popular to make the most internal layer of the shields.

    Tungsten Evaporation Source

    Tungsten sheet is a popular material to use as an evaporation boat due to its very high melting point, low vapor pressure and stable chemical properties under high temperature. During the evaporating process, tungsten can ensure no impure particles enter the vapor and penetrate the layer adhering to the base.
